3.2 Reset RX Detect State Machine

The RX Detect State Machine may be manually reset for all channels.

Table 3-4 Sequence to Reset RX Detect State Machine
Step Register Set Operation Register Address [HEX] Register Value [HEX] Write Mask [HEX] Comment
1 Bank 0: Channels 0-3 Write 0x89 0x04 0x04 Set RX Detect Reset bit to: 1 (Reset RX Detect State Machine)
2 Bank 1: Channels 4-7 Write 0x89 0x00 0x04 Set RX Detect Reset bit to: 0 (Clear set bit)

Assuming 0x18 and 0x19 are the I2C / SMBus addresses for the Channel Banks 0 and 1 respectively, the following is the XML batch script of the sequence in Table 3-4 to reset the RX Detect state machine on all channels:

<i2c_write addr="0x18" count="0" radix"16">89 04</i2c_write>
<i2c_write addr="0x19" count="0" radix"16">89 04</i2c_write>
<i2c_write addr="0x18" count="0" radix"16">09 00</i2c_write>
<i2c_write addr="0x19" count="0" radix"16">09 00</i2c_write>
